I can help you about Products and Services in QuickBooks Online, Jojo.

I understand the significance of pricing for products and services. I'd like to offer some insights on this topic.

In QuickBooks Online (QBO), it is not possible to automatically mark an invoice or set the product price of products and services to zero. I recommend we manually enter each item according to the price rules you have established.

For guidance on applying price rules while creating an invoice, you can refer to this article: Set price rules in QuickBooks Online.

Once everything is complete, you can streamline your transaction categorization process by setting up bank rules for online banking transactions in QuickBooks Online. For more information on how to do this, refer to the article: Set up bank rules to categorize online banking transactions in QuickBooks Online.

If you have any more questions about products and services in QBO, please feel free to reach out. I'm here to provide support.
